Utilization of MOSFET transistor as an electronic load to trace I-V and P-V curve of a solar panel

Abstract

To understand the electrical behavior of a photovoltaic panel, it is necessary to know the characteristic Ipv = f(Vpv). The best way to obtainthis I-V curve is to use a variable resistor. This paper proposes a new and simple technique based on a MOSFET transistor as a variable load, which whose gate voltage is controlled by an RC filter from the Arduino. A comparison under standard temperature and illumination conditions between the manufacturer’s datasheet with the simulation by MATLAB/Simulink on the one hand, and on the other hand between the manufacturer’s datasheet with the experimental data for the evaluation of this technique that has been performed.
